For generations, Mossberg has built reliable, quality firearms at an unparalleled value and with the 100 ATR, they deliver high performance without the high maintenance. Widely popular calibers and a free-floating, button-rifled barrels combine to deliver a high level of accuracy unheard of in a value-priced centerfire rifle. A side lever safety is utilized for convenience and safety afield and the all-steel, machined receiver provides the 100 ATR with positive lock-up for consistent operation. The integral synthetic trigger guard allows for easy cleaning and maintenance, while the rubber recoil pad aids recoil reduction and stable positioning.

The Mossberg ATR Deer Thug Rifle comes with the Deer Thugs logo engraved on its stock. The Thugs rifle also features a fluted barrel, Mossberg's adjustable LBA trigger, and a top-loading magazine. The gun is finished in Mossy Oak Infinity camo and comes with a sling.
